TL;DR: This is the first genome sequence of a Desiccation-tolerant extremophile, offering insight into the evolution of this important trait and a first look into the genome organization of desiccation tolerance.
Abstract: “Drying without dying” is an essential trait in land plant evolution. Unraveling how a unique group of angiosperms, the Resurrection Plants, survive desiccation of their leaves and roots has been hampered by the lack of a foundational genome perspective. Here we report the ∼1,691-Mb sequenced genome of Boea hygrometrica, an important resurrection plant model. The sequence revealed evidence for two historical genome-wide duplication events, a compliment of 49,374 protein-coding genes, 29.15% of which are unique (orphan) to Boea and 20% of which (9,888) significantly respond to desiccation at the transcript level. Expansion of early light-inducible protein (ELIP) and 5S rRNA genes highlights the importance of the protection of the photosynthetic apparatus during drying and the rapid resumption of protein synthesis in the resurrection capability of Boea. Transcriptome analysis reveals extensive alternative splicing of transcripts and a focus on cellular protection strategies. The lack of desiccation tolerance-specific genome organizational features suggests the resurrection phenotype evolved mainly by an alteration in the control of dehydration response genes.

TL;DR: The genus Kaisupeea is established for Boea herbacea, a species long recognised as being out of place in Boea, and two new species closely allied to it, which produce annual flowering stems whose basal leaves may be represented by broad foliaceous cataphylls.

TL;DR: The genus Boea Comm.
Abstract: The genus Boea Comm. ex Lam. is revised. Eleven species are recognised, including the new species Boea morobensis C.Puglisi. A key is provided, all names are typified, and the species are described.
